On the Klein-Gordon G\"{u}rses-oscillators and pseudo-G\"{u}rses-oscillators: vorticity-energy correlations and spacetime associated degeneracies

TL;DR

This paper investigates Klein-Gordon oscillators in G"{u}rses spacetime, revealing vorticity-energy correlations and degeneracies, and introduces pseudo-G"{u}rses oscillators with similar spectral properties and invariances, correcting prior misinterpretations.

Contribution

It provides a detailed analysis of KG-G"{u}rses oscillators, clarifies previous results, and introduces new pseudo-G"{u}rses oscillators with isospectrality and invariance.

Findings

KG-G"{u}rses oscillators exhibit vorticity-energy correlations.

Spacetime associated degeneracies (STAD) are present in the energy spectrum.

New pseudo-G"{u}rses oscillators are isospectral and invariant with KG-G"{u}rses oscillators.

Abstract

We discuss KG-oscillators in the (1+2)-dimensional G\"{u}rses spacetime and under position-dependent mass (PDM) settings. We observe that the KG-G\"{u}rses oscillators are introduced as a byproduct of the very nature of the G\"{u}rses spacetime structure. We report that the energy levels of such KG-G\"{u}rses oscillators admit vorticity-energy correlations as well as spacetime associated degeneracies (STAD). We discuss KG-G\"{u}rses oscillators' results reported by Ahmed \cite{Ahmed1 2019} and pinpoint his improper treatment of this model so that his results should be redirected to those reported in this study. Moreover, we introduce a new set of KG pseudo-G\"{u}rses oscillators that admits isospectrality and invariance with the KG-G\"{u}rses oscillators and inherits the same vorticity-energy correlations as well as STADs.
